Figure 1

The ERP waveform at electrode site Pz, where P3 was evaluated as the latency marking 50% of the area under the P3 curve. Deciding whether a presented number was negative was least difficult and had the earliest P3 latency. Deciding whether the number was odd had middling difficulty and P3 latency. Deciding if the number was in one of two divergent parts of the number line (i.e., Complex) was most difficult and had the longest P3.
